"Detecting the Invisible" - Scientific and Environmental Remote Sensing at Surrey

 Abstract

Over the past decade, Surrey Space Centre (SSC) has developed and flown a number of compact, ultra-low-cost scientific instruments for environmental monitoring. The visible/near-IR imaging capability of Surrey's satellites is now well known, however, the author's primary interest lies in the detection of the "invisible" radiations - in particular sub-atomic particles and UV light. This lecture will outline how SSC's approach of adapting commercial-off-the-shelf technologies has allowed Surrey's microsatellites to make a significant contribution to the understanding of the near-Earth ionising radiation environment and its effects, and more recently has begun to examine other phenomena such as global total ozone concentration, the cryosphere, and global cloud coverage - all at a tiny fraction of the cost of traditional spacecraft instrumentation. Results and applications will be presented for the CREDO/CRE/CEDEX radiation monitors flown on the UoSAT-3, KITSAT-1, PoSAT-1, TiungSAT and Phase 3D missions, and the OMAD UV-radiometer flown on FASAT-Bravo.
